METHOD FOR PROVIDING FREE CALL THROUGH TEXT MESSAGE, SERVER AND SYSTEM

摘要

A method for providing a free call through a text message may comprise the following steps of: confirming whether a transmitting number of a text message is a number purchased by a company; transmitting, to a customer terminal, a text message containing a call identifier and the transmitting number when the transmitting number is the number purchased by a company; receiving an outgoing call from the customer terminal; identifying whether or not the call identifier is included in recipient information of the outgoing call; and connecting a call to a dialed number excluding the call identifier.
